I assumed you would post like you did if you had any questions.



Files I attached allow you to use a different slicer to slice the models for your Davinci Jnr 1.0. 1st unzip the files to a folder to allow access.
I would suggest starting by download Prusaslicer 2.3.0 an install the program.
Start the Prusaslicer 2.3.0. Select File > Import > Import Config : locate and select Dav_VanciI_1.0_AIO.ini PrusaSlicer is ready to select a model ans slice for Dav_VanciI.

This should allow you to slice a model an 3D Print with your Davinci Jnr 1.0.
